The ultimate test a self-driving car will need to pass before I buy one-- since I plan on going here once I have a self-driving car-- are the switchbacks located near 125 Green River Cove Rd, Saluda, NC 28773. Those are INSANE. Which makes it a wonderful testing place to certify self-driving cars are up to real-world challenges. Just puttin' it out there...

Oh... maybe never mind. There's so many other good testing places as well...
